16-4-8 (120 day) Fertility Trial, Lantana
Dr. John Olive and Dr. Charles Gilliam, Auburn University, Ornamental Horticultural Research Center, Mobile, Alabama, 2008
The trial herein is predicated on the work of Tyler et al. (1993) and was designed to evaluate the effect of Suståne® 16-4-8 (120 day) controlled release fertilizer on plant performance of ‘New Gold’ lantana. More than half of Suståne 16-4-8 is composed of an all natural fertilizer derived from aerobically composted turkey litter. The trial compared Suståne 16-4-8 (120 day) to an industry standard 15-9-12 (8-9 mo.) controlled release fertilizer. Each fertilizer was incorporated at a rate of 1.5 pounds of nitrogen per cubic yard. The potting medium was a 3:1 mix (by volume) of pine bark and peat.
